Sizing a central AC unit for a Cleveland County home means accounting for a real cooling load, not a marginal one. Homes in Cleveland County, AR run cooling about five months a year, from May through September. The compressor starts and stops on a schedule like that from May through every hot week of September, and a unit that was undersized at install or had its refrigerant charge set loose will show the consequences in its contactor, its capacitor, and eventually its compressor body itself. A contractor quoting a new system here has to run a proper load calculation before settling on equipment, because an undersized unit that short-cycles through a season this length wears through its starting components faster than one sized to the actual heat load of the house.
Ductwork in a house does not get replaced on a schedule. It stays until something forces the issue, and in Cleveland County a significant share of the housing stock has duct runs, trunk sizes, and return configurations that were laid out for equipment with different airflow demands than what a contractor is installing today. Half the homes in Cleveland County, Arkansas were built in 1987 or earlier (2020-2024 ACS 5-year). A modern central AC system moving air through passages sized for an older load will not perform to its rated capacity, and the electrical service feeding the new unit is a second question a contractor has to answer before the equipment is ever ordered.
What Gets Installed With a New Central AC
The outdoor condenser unit sits outside the house, usually on a concrete pad along an exterior wall, and it holds the compressor and the condenser coil. Inside, the air handler or furnace cabinet stands in a utility closet, basement, or attic and circulates air through the home. These two units are the core of what a contractor brings to the job.
A copper refrigerant line set runs between the indoor and outdoor units, and a condensate drain line carries moisture away from the air handler to a floor drain or outside. The thermostat mounts on an interior wall and gives the homeowner control over the whole system.
The drawing shows a typical layout, and a licensed contractor determines exactly what fits this house and how each piece connects.

What the Installation Actually Looks Like
Split-system central air conditioners rated below 45,000 Btu/h manufactured on or after January 1, 2023 must meet a federal minimum of 13.4 SEER2.
Split-system central air conditioners rated at or above 45,000 Btu/h manufactured on or after January 1, 2023 must meet a federal minimum of 13.4 SEER2.
Split-system central air conditioners manufactured between January 1, 2015 and December 31, 2022 had to meet 13 SEER, the metric that preceded SEER2.
Single-package central air conditioners manufactured on or after January 1, 2023 must meet a federal minimum of 13.4 SEER2.
Space-constrained central air conditioners manufactured on or after January 1, 2023 must meet a federal minimum of 11.7 SEER2.
Federal efficiency standards for split-system central air conditioners and heat pumps are set on each certified combination of outdoor unit and indoor coil rather than on the outdoor unit alone.
Residential and light commercial air conditioning and heat pump systems assembled in the field, including mini-splits and unitary systems, may not be installed on or after January 1, 2025 using a refrigerant with a global warming potential above 700.
A field-assembled system whose specified components were all manufactured or imported before January 1, 2025 carries no installation compliance date under the refrigerant restrictions and may still be installed.

Severe Weather Events in Cleveland County
Weather puts real load on cooling equipment, and that load is specific to where the system lives. A unit sized and installed for what Cleveland County actually sees will run differently than one spec'd from a national average.
